INSTEP-SUPPORT OR ARCH-PROP.

Specification of Letters Patent.

Patented June 80, 1908.

Application filed April 2, i906. Serial No. 309,327.

To, all whom it may concern:

Be it known that I, LEON T. J. Learn, a citizen of the United States, residing at Boston, countyof Suffolk, andState of Massachusetts, have invented an Improvement in Inste -Supports or Arch-Props, of which the description, in connection with the accompanying drawing, is a specification, like letters on the drawings representing like )arts. 1 This invention has for its object the roducprop, pro or the heel is provide( with a wherein theinner on of the arch end farthest from the foot which adds materially to the stiffness at that end of the arch rop with relation to its at end of the arch prop may be raised more or less as is frequently necessary to adapt the arch prop to the requirements of the foot. The rear or heel end of the arbh prop is provided witha spring portion integral with the nietalforniing the arch prop, said spring serving to throw the arch pro pressure away from the foot when the weig t is removed.

Figure 1 shows an inner side elevation of an arch prop embodying in invention; Fig. 2 is a bottom side view of ig. 1; Fig. 3 is a section on the line :0, Fig. 2, and Fig. 4 is a cross section on the line as, Fig. 1, looking to ward the left.

The instep or arch prop herein represented comprises a sheet metal body part a and a non-metallic top or cover part of leather or other usual material I), said parts being attached one to the other by rivets c. The bod part of the arch prop, which gives shape to t e same, is curved in the direction of its len th and width to fit the hollow of the foot or the under surface of the normal arch of the inste a portion of said body part at its inner edge being curved upwardly to resent a concaved part next the instep of t e foot. The

front or inner end of the arch prop isshown as provided'with a foot athat crosses said arch prop- The foot may be so arated more or essffrom the under side of the body part overlying the same to leave as shown, a free space between the inner end of the body part sharp and the overlying top art or cover. The foot is shown as formed by bending the front end of the arch prop downwardl and back wardlyonitself. Bendingthc are i prop backwai'dly in forming the foot leaves the arch mm of such construction and shape at its front end that it cannot cut the leather forming the sole of the shoe.

in practice the bend 2 may be more or less to locate the foot at the distance desirei with relation to the body of the arch prop thereabove according to the shape of the foot and the requirements for its proper su ort.

1 ie metal of the arch prop may be more or less stiff, and in some instances it may be s'uch as to permit the foot to yield somewhat. The crosswise foot adds to the stiffness cr0sswise of the arch prop at its front end, and this foot may be bent to change the height of the central art of the prop with relation to the sole of the shoe. 1 The rear end of the arch prop is slitted at 3, the slit being shown as circular, and the metal 4 within the circular sli-t is elevated as shown in I igs. 1 and 3 to form a spring member onwhich rests the under side of the leather top piece b with which the heel of the person wearing 'the shoe aving the arch prop contacts. The meta 4 constituting the sprin sustains the wei ht of the foot when wallring, and when t 1e foot is lifted frpin the ground, the spring resumes itsnormal position Fig. 1, and servesto remove the pressure of the top part b ofthe prop from the arch'of the foot.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:-

1. As an article of manufacture an instep support or arch rop comprisin a metallic body portion s ia ed longitu ally and transversely to fit the arch of the foot, said arch lprop being bent downwardl and backward y across one end to form a oot the free end of whichiis normally out of contact with the inider side of the arch prop and in front of the median transverse line thereof. l

2. A metallic arch prop bent downwardly Q l r 892,086
